.The operation will` be-asfollowsi The "terial to be treated Vwill be `fedin'to the rhopi per 16 and conveyed thence to the chutef,from

which it will fall to the plate 18, and the blades 17 will move it along toward the other end of the chamber F. The chamber I will bekept constantly charged with air under pressure, which will `pass through the slots or perforations in the plate 18 with suflcient force or velocity to, carry the seeds with it upwardly against the inclined side b of the casing, and they will be deflected to the other side of the plate ll and fall onto theplate 20 in the cham ber G, and the blades 2l will move it along to the outlet-opening provided for its discharge. The air in the meantime will escape through the perforated plate y into the conduit B and out through the pipe C. The blades 17 being separated from each other will keep the material stirred up and agitated while moving it along,and thereby separate the seeds one from the other in case they have become matted together, which is frequently the case with cotton-seed. A 'continuous spiral blade would not eect this result. As the material is moved along the plate 1S from the feed end of the casing the seed will be gradually blown away from the stones, dac., and only the latter will remain to be discharged from the outlet-opening of the chamber F. The deflecting-plate ll will prevent the seeds from striking the inclined side at too high a point, and the limit of the striking-point can be varied by adjusting the plate l1. There will be considerable dust and other light impurities carried'upward with the air from the material being treated, and in the case of cotton-seed there will be some lint, and while much of the dust will pass through the perforated plate y the lint and othel particles will collect upon said plate-and tend to choke the perforations unless they are removed. Various devices might be employed for this purpose, and as illustrative thereof I have shown a series of slats or Scrapers 25, connected to endless bands or belts 26 and forming practically a-V slat belt. The belts are mounted upon pulleys 27 on shafts 28, one of which will be positively driven by any suitable means, and thereby drive the slatted belt. The latter will beso supported that the front edges of the slats will scrape over the plate y, and thus remove any matter tending to adhere to it. Such matter may be permitted to fall into the chamber G or into a trough 29, from whence it maybe removed at intervals.

Without limiting myself to the precise d`etails illustrated and described, I claiml. In an apparatus for separating stones, dto., from seed, the combination of an inclosing casing having a vertical partition dividing it into two chambers, a perforated plate supported in one chamber above the bottom thereof, means to feed the material to be treated onto one end of said plate, means to move it along said plate, means for introducing air under pressure below said perforated plate, and means to deflect the seed carried v up by the air from the perforated plate into the other chamber, substantially as set forth.

2. In an apparatus for separating stones, dac., from seed, the combination of an inclosing casing having a cover formed of inclined sides, a vertical partition dividing said cas' inginto two chambers communicating at their upper portions, a perforated plate in one chamber above the'bottom thereof, means to feed the material to be treated to one end of said plate, means to move the material along said plate, means for introducing air under pressure below said plate, and a perforated plate in the upper part of the casing for the exit ofthe air, substantially as set forth.

In an apparatus for separating stones, dac., from seed,`tl1e combination of an inclosing casing having a cover formed of inclined sides, avertical partition dividing said casing into two chambers com m unicating at their upper portions, a `deflecting-plate hinged to the upper edge of said partition and inclined over one chamber, a perforated plate supported in the latter chamber above the bottom thereof, means to feed the material to be treated to one end of said plate, means to move the material along said plate, meansfor introducing air under pressurebelow the said plate, and an air-exit in the inclined side of the roof above the otherchamber, substantially as set forth.

4. In an apparatus for separating stones, dsc., from seed, the combination of an inclos- `ing casing having a vertical partition dividing it into two chambers, a perforated plate supported in one chamber above the bottom thereof, means to feed the material to be treated to one end of said plate, a shaft journaled above said plate, a series of separated blades connected to said shaft and arranged spirally thereon to move the material along said plate, means for introducing air under pressure below said plate, and means to defiect the seed carried up by the air into the other chamber, substantially as set forth.

5. 'In an apparatus for separating stones, circ., from seed, the combination of an inclos.- ing casing having a vertical partition dividing it into two chambers, a perforated plate supported in one chamber above the bottom thereof, means to deliver the material to' be treated to one end of said plate, means to move the material along said plate, means for introducing air under pressure below the plate, means to detiect the seed carried up by the air into the other chamber, a perforated plate in said casing for the exit of the air, and means to remove material tending to adhere to the latter plate, substantiallyl as setA forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
